Currently I'm running with pacman 3.1 using wget-xdelta.sh as an alternate transfer method. I was a little surprized to get a delta download for pacman-git, pacman-git-20071107-1_to_20071108-1-i686.delta saving 1.1Mb on a 1.3Mb file. Applying delta... 1133389 bytes saved by xdelta. Then, I was a little bit surprized to not get a delta for Nathan's delta-test: http://home.insightbb.com/~nathanj/dt/deltatest-1.0.1-2_to_1.0.2rc3-1-i686.d... => `deltatest-1.0.1-2_to_1.0.2rc3-1-i686.delta' Resolving home.insightbb.com... 74.128.0.22 Connecting to home.insightbb.com|74.128.0.22|:80... connected.
